nfs mount..

Hello I'm trying to build a music mpd server. I have bought a usb audio sound card..Ok
my problem is that the music is on a nfs server, but I have install nfs utils.. and when imount.nfs4 ip:/folder local_folder
it give me this output.mount.nfs4: No such device

Ahh OK then yeah the firmware must be compiled with those driver enabled.
Have you tried compiling the firmware? There is a post here on how to use Docker and a pre-built image that a community member has built.

I was able to compile my own firmware and saw the options to include the kernel driver AS seen in the image below. If you can get the Docker image (or other way) to compile the firmware; you could also include this kernel driver in the firmware and flash and test it.

Below is the Omega2 firmware 'make menuconfig' option showing the nfs file system kernel driver. If you want, I can try to take the defaults and add this driver in and build the firmware. I could then host it on my GitHub and you could download and try to flash it from there. Would just take me a bit of time but BE FORE WARNED that while I'm sure I could get it to compile, and have done it with other OpenWRT builds and boards; I cannot say it won't strand you but making the device unusable. All attempts at this source is to share with the community BUT you take all risks in knowing how, what to do if problems occur.

Let me know and I can compile for you with some options (if you know them) and the nfs module and you could test.
Cheers,

BEWARE, however, that I may not be able to help you get back to default firmware if something goes wrong with the flash but I have helped someone recover their Omega2+ from constant reboot due to a bad firmware from Onion.

If we get to that point, let me know and we can help you with a dock and USB if you have them. If not, you may have to use a TTL2USB adapter and go serially. This would be NO different if you flashed a bad firmware from Onion so while I give you the BEWARE it's something you may have to do eventually, lol..

As for the WiFi driver I'm not sure. I used what was packaged in the Docker image from another user. If by chance you have used Docker the image is pretty straight forward and once you build the toolchain & tools binaries (which takes me about 1 hour roughly on an 6/12 core i7 49230K @ 3.4ghz) it builds in roughly 20 mins thereafter. If not Docker, you should still be able to use Linux and pull the source but you'll have to do some configuration up-front.

Also, below is the driver that came 'stock' setup in the firmware.. If you deduce which one you wish to try let me know and I can attempt to merge in and rebuild for you. Lastly, Omega2 or 2+ just in case we do get to rebuild it for you :)
